utest: ado-file for testing for a U-shape

[Halvor Mehlum <halvor.mehlum@econ.uio.no>]

Dear Statalisters

Thanks to Kit Baum, -utest- ado-file is now available from SSC.

-utest- provides the exact test of the presence of a U shaped (or
inverse U shaped) relationship on an interval. -utest- is used after 
estimation commands to test for the presence of a U-shaped or
inverse U-shaped relationship between an explanatory variable and the 
outcome variable on a specific interval.

For details see:

For the companion paper
"With or Without U? - The appropriate test for a U shaped relationship" see:

All the best
Jo Thori Lind and Halvor Mehlum
